如何获得iPhone通讯录联系人的电子邮件NSStrings？ [英] How to get an iPhone address book contact's emails as NSStrings?

问题描述

我知道电子邮件可以有多个值，但我不知道如何浏览这些值。

我可以正确得到一个人。 / p>

  ABRecordRef person = //取得某人
 NSString * emails =（NSString *）ABRecordCopyValue（person，kABPersonEmailProperty）; 
  

...下一步是什么？如果我尝试打印电子邮件变量，我得到：

 电子邮件： < NSCFType：0x4018d40> 
  

解决方案

这是因为电子邮件不应是字符串，数组。人们可以有很多电子邮件！

  ABMultiValueRef emails = ABRecordCopyValue（person，kABPersonEmailProperty）; 
 CFStringRef email = ABMultiValueCopyValueAtIndex（emails，< INDEX>）; 
 NSLog（（NSString *）email）; 
  

这里是一些关于MultiValueLists可以做的事情的文档

I know that there can be multiple values for an email, but I'm not sure how to browse through them.

I can get a person correctly.

ABRecordRef person = // getting a person;
NSString* emails = (NSString *)ABRecordCopyValue(person, kABPersonEmailProperty);

... what's next? If I try to print the emails variable I get:

Emails: <NSCFType: 0x4018d40>

解决方案

It is because emails should not be a string, but an array. People can have many emails!

ABMultiValueRef emails = ABRecordCopyValue(person, kABPersonEmailProperty);
CFStringRef email = ABMultiValueCopyValueAtIndex(emails, <INDEX>);
NSLog( (NSString *) email);

Here are some docs on things you can do with MultiValueLists
